Male breast cancers :- Infiltrating ductal carcinoma: Cancer that has spread beyond the cells lining ducts in the breast. Most men with breast cancer have this type of cancer.
- Ductal carcinoma in situ: Abnormal cells that are found in the lining of a duct; also called intraductal carcinoma.
- Inflammatory breast cancer: A type of cancer in which the breast looks red and swollen and feels warm.
- Paget’s disease of the nipple: A tumor that has grown from ducts beneath the nipple onto the surface of the nipple.
Lobular carcinoma in situ (abnormal cells found in one of the lobes or sections of the breast), which sometimes occurs in women, has not been seen in men. Radiation exposure, high levels of estrogen, and a family history of breast cancer can affect a man’s risk of developing breast cancer. Risk factors for breast cancer in men may include the following: - Exposure to radiation.
- Having a disease related to high levels of estrogen in the body, such as cirrhosis (liver disease) or Klinefelter’s syndrome (a genetic disorder).
- Having several female relatives who have had breast cancer, especially relatives who have an alteration of the BRCA2 gene.
Male breast cancer is sometimes caused by inherited gene mutations (changes). |
